NELSON — A Windham man who is accused of killing a 1-year-old boy by throwing him against a wall is being held on a $1 million bond.

Nicholas J. Catazaro, 26, was arraigned Tuesday afternoon in Portage County Municipal Court in Ravenna. If convicted, he could be sentenced to 15 years to life in prison.

Catazaro was arrested early Sunday morning. According to the complaint filed Tuesday, the incident happened Friday at a mobile home on Bayberry Lane, just north of Nelson Ledges Quarry Park.

Portage County sheriff’s deputies were called to the address at about 12:30 a.m. Saturday along with an EMS squad for a 1-year-old boy who was not breathing, according a news release from the Portage County Sheriff’s Office. The release said CPR was being performed on the child when deputies and EMS arrived. He was pronounced dead at University Hospitals Portage Medical Center.

An autopsy by the Cuyahoga County Medical Examiner’s office found that the boy had a fractured skull. According to the complaint, Catazaro threw the boy against a wall.

A neighbor said the boy and his mother moved into the mobile home park about two months ago. The relationship between Catazaro and the boy was not publicly known Tuesday.

Catazaro did not speak during the hearing. Judge Barbara Oswick also imposed other conditions requested by Assistant Prosecutor Jared Smiley, including that if Catazaro is released on bond, he would be ordered to have no contact with the boy’s family, their property or any other juveniles. He also would be required to wear a GPS monitoring device.

A preliminary hearing in the case is scheduled for Friday.
